    Description copied from class: BaseJsonNode
    
    Method that can be used for efficient type detection when using stream abstraction for traversing nodes. Will return the first JsonToken that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple)
    
    Specified by:

    Specified by:

  - numberType
```
public com.fasterxml.jackson.core.JsonParser.NumberType numberType()
```
    Description copied from class: BaseJsonNode
    
    Returns code that identifies type of underlying numeric value, if (and only if) node is a number node.
    
    Specified by:
    
    numberType in interface com.fasterxml.jackson.core.TreeNode
    
    Specified by:
    
    numberType in class NumericNode
  - isFloatingPointNumber
```
public boolean isFloatingPointNumber()
```
    Overrides:
    
    isFloatingPointNumber in class JsonNode
    
    Returns:
    
    True if this node represents a non-integral numeric JSON value
  - isBigDecimal
```
public boolean isBigDecimal()
```
    Overrides:
    
    isBigDecimal in class JsonNode
  - canConvertToInt
```
public boolean canConvertToInt()
```
    Description copied from class: JsonNode
    
    Method that can be used to check whether this node is a numeric node (JsonNode.isNumber() would return true) AND its value fits within Java's 32-bit signed integer type, int. Note that floating-point numbers are convertible if the integral part fits without overflow (as per standard Java coercion rules)
    NOTE: this method does not consider possible value type conversion from JSON String into Number; so even if this method returns false, it is possible that JsonNode.asInt() could still succeed if node is a JSON String representing integral number, or boolean.
    
    Specified by:
    
    canConvertToInt in class NumericNode
  - canConvertToLong
```
public boolean canConvertToLong()
```
    Description copied from class: JsonNode
    
    Method that can be used to check whether this node is a numeric node (JsonNode.isNumber() would return true) AND its value fits within Java's 64-bit signed integer type, long. Note that floating-point numbers are convertible if the integral part fits without overflow (as per standard Java coercion rules)
    NOTE: this method does not consider possible value type conversion from JSON String into Number; so even if this method returns false, it is possible that JsonNode.asLong() could still succeed if node is a JSON String representing integral number, or boolean.
    
    Specified by:
    
    canConvertToLong in class NumericNode
  - canConvertToExactIntegral
```
public boolean canConvertToExactIntegral()
```
    Description copied from class: JsonNode
    
    Method that can be used to check whether contained value is numeric (returns true for JsonNode.isNumber()) and can be losslessly converted to integral number (specifically, BigInteger but potentially others, see JsonNode.canConvertToInt() and JsonNode.canConvertToInt()). Latter part allows floating-point numbers (for which JsonNode.isFloatingPointNumber() returns true) that do not have fractional part. Note that "not-a-number" values of double and float will return false as they can not be converted to matching integral representations.
    
    Overrides:
    
    canConvertToExactIntegral in class JsonNode
    
    Returns:
    
    True if the value is an actual number with no fractional part; false for non-numeric types, NaN representations of floating-point numbers, and floating-point numbers with fractional part.
  - numberValue
```
public Number numberValue()
```
    Description copied from class: JsonNode
    
    Returns numeric value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true); otherwise returns null
    
    Specified by:
    
    numberValue in class NumericNode
    
    Returns:
    
    Number value this node contains, if any (null for non-number nodes).
  - shortValue
```
public short shortValue()
```
    Description copied from class: JsonNode
    
    Returns 16-bit short value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns 0. For floating-point numbers, value is truncated using default Java coercion, similar to how cast from double to short operates.
    
    Overrides:
    
    shortValue in class JsonNode
    
    Returns:
    
    Short value this node contains, if any; 0 for non-number nodes.
  - intValue
```
public int intValue()
```
    Description copied from class: JsonNode
    
    Returns integer value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns 0. For floating-point numbers, value is truncated using default Java coercion, similar to how cast from double to int operates.
    
    Specified by:
    
    intValue in class NumericNode
    
    Returns:
    
    Integer value this node contains, if any; 0 for non-number nodes.
  - longValue
```
public long longValue()
```
    Description copied from class: JsonNode
    
    Returns 64-bit long value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns 0. For floating-point numbers, value is truncated using default Java coercion, similar to how cast from double to long operates.
    
    Specified by:
    
    longValue in class NumericNode
    
    Returns:
    
    Long value this node contains, if any; 0 for non-number nodes.
  - bigIntegerValue
```
public BigInteger bigIntegerValue()
```
    Description copied from class: JsonNode
    
    Returns integer value for this node (as BigInteger), if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns BigInteger.ZERO.
    NOTE: In Jackson 2.x MAY throw StreamConstraintsException if the scale of the underlying BigDecimal is too large to convert (NOTE: thrown "sneakily" in Jackson 2.x due to API compatibility restrictions)
    
    Specified by:
    
    bigIntegerValue in class NumericNode
    
    Returns:
    
    BigInteger value this node contains, if numeric node; BigInteger.ZERO for non-number nodes.
  - floatValue
```
public float floatValue()
```
    Description copied from class: JsonNode
    
    Returns 32-bit floating value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns 0.0. For integer values, conversion is done using coercion; this means that an overflow is possible for `long` values
    
    Overrides:
    
    floatValue in class JsonNode
    
    Returns:
    
    32-bit float value this node contains, if any; 0.0 for non-number nodes.

public double doubleValue()
```
    Description copied from class: JsonNode
    
    Returns 64-bit floating point (double) value for this node, if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns 0.0. For integer values, conversion is done using coercion; this may result in overflows with BigInteger values.
    
    Specified by:
    
    doubleValue in class NumericNode
    
    Returns:
    
    64-bit double value this node contains, if any; 0.0 for non-number nodes.
  - decimalValue
```
public BigDecimal decimalValue()
```
    Description copied from class: JsonNode
    
    Returns floating point value for this node (as BigDecimal), if and only if this node is numeric (JsonNode.isNumber() returns true). For other types returns BigDecimal.ZERO.
    
    Specified by:
    
    decimalValue in class NumericNode
    
    Returns:
    
    BigDecimal value this node contains, if numeric node; BigDecimal.ZERO for non-number nodes.
  - asText
```
public String asText()
```
    Description copied from class: JsonNode
    
    Method that will return a valid String representation of the container value, if the node is a value node (method JsonNode.isValueNode() returns true), otherwise empty String.

    asText in class NumericNode
  - serialize
```
public final void serialize(com.fasterxml.jackson.core.JsonGenerator g,
                            SerializerProvider provider)

    Throws:
    
    IOException
  - equals
```
public boolean equals(Object o)
```
    Description copied from class: JsonNode
    
    Equality for node objects is defined as full (deep) value equality. This means that it is possible to compare complete JSON trees for equality by comparing equality of root nodes.
    Note: marked as abstract to ensure all implementation classes define it properly and not rely on definition from Object.

public int hashCode()
```
    Specified by:
